I had a toenail fungal infection for about 3 years, only on one big toe, I went to the doctors about an unrelated problem, a yeast infection in the groin, known as 'jock itch', he gave me some ointment for the jock itch and on reading the leaflet noticed that it said 'also for treatment of nail fungus, I applied the ointment to my toe and within about 3 or 4 months the nail was fine, it grew out and is now normal. For the life of me I cannot remember the ointments name, but you maybe ought to consider getting something similar from your GP or pharmacy.
